Best not to mess with this MMA tyke on the playground

Probably not a good idea to step into the Octagon with this kid (h/t Deadspin). Low center of gravity and all. Imagine the damage he can do to a full-grown opponent's family jewels. Plus, his duck-and-slip game is off the charts. A word to the wise for all the playground bullies out there: Best stop handing out wedgies now for fear of MMA retaliation.

The Daily Mail recently estimated 3 million children compete in mixed martial arts on a weekly basis, including one by the name of Kris "The Arm Collector" Arrey. I don't know what this kid's nickname is, but he sure looks like a Chuck Little or Infant Ivan Drago.
